Prepare for another alien invasion in the energetic sequel slot Reactoonz 2! Released by Play'n GO in 2020, just 3 years after the original, this game features a plethora of colourful and somewhat cute aliens who are all vying to group together and send wins streaming into your bankroll! Bursting with cascading wins, four different wild symbols and two fillable meters, Reactoonz 2 offers a unique setup with its 7x7 grid layout.

Overview of Reactoonz 2

Alien symbols fall into place from above with clusters of 5 or more paying out before disappearing and being replaced by more, leading to those much loved chain reaction wins. These are what will charge the two meters, which ultimately lead to explosive winning effects on the play grid! This enthralling gameplay is intensified by blips, boings and babbles from the aliens and a soundtrack that builds from simple electro to complex trancey synthpop as you progress. This is one game you don't want to miss! Read on to find out more.

Reactoonz 2 Theme

If you're not familiar with the original game Reactoonz, this sequel features the same comical alien invasion of amusing one, two and three eyed creatures of various colours. The one and two-eyed aliens are the main symbols in this game, which cascade into place on a 7x7 grid with each 'spin'. Rather than running on set paylines, this game pays out when you get a cluster of 5 or more matching symbols touching each other, resulting in wins of up to 500x your bet. Each time you win, the symbols involved disappear and are replaced by more from above, resulting in a potential chain reaction of wins!

The four two-eyed aliens are the highest paying symbols in the game, with the four one-eyed aliens paying out the least. However, these one-eyed aliens have their own role to play in this game, as we'll see later!

As in the original game, the three-eyed Gargantoon waits at the side of the reels, but this time he's joined by a new alien with a W on his head, hinting at the effect he has on the reels!

Sound and Soundtrack

As you play, various dazzling cosmic sounds add depth and emotion to the experience, from the blippy noise as the symbols fall into place to shock boing sounds as matching symbols are highlighted and disappear. One-eyed alien charges emit a climbing tinkly sound while charges to the Gargantoon and Energoon meter result in a zooming sound effect. Every now and then you'll hear a brief babble of alien-speak from one of the creatures, adding a comical feel to the game.

The musical soundtrack of the game injects an increasing amount of energy and intensity into the experience. Starting with a gentle plunking of a simple electro melody with rhythm hi hat, the music builds to an upbeat trancey synthpop with a multitude of melodies and backing as you progress through the game, making it a thrill to play!

Bonus Feature

Reactoonz 2 is bursting with various effects and special features, which is what makes the game such an exciting experience. When you trigger a cascade of wins and all the other various effects start coming into play too, it really gets the adrenalin pumping! Let's take a look at the various special effects you'll find in this game.


Each time you hit the spin button, the Fluctometer (the circle to the right of the reels) shows a different one-eyed alien, which will be that round's fluctuating symbol. If you get a winning cluster with these fluctuating symbols, an electric wild symbol is created, which appears where the winning cluster was. In addition, each winning fluctuating symbol adds a charge to the Fluctometer. Fill it up in one round and you'll also get 1, 2 or 3 electric wilds added to the play grid!


Under the Fluctometer is the Quantumeter, where the three-eyed alien and the dark blue W alien are waiting. Each electric wild win adds a charge to the Quantumeter, which has four different levels. Fill the meter to unleash the special effects of each level:

  • Level 1: Four Energoon wilds will be added to the play grid
  • Level 2: A 2x2 Energoon wild symbol will be added
  • Level 3: A massive 3x3 Gargantoon wild will be added, which then changes into two 2x2 Gargantoon wilds before turning into nine single Gargantoon wild symbols
  • Level 4: Same as level 3 but with all wins doubled!

Uncharged Wilds

Electric wilds are noticeable by their electric appearance, but there are also uncharged wilds in this game. These can be turned into electric wilds if they are next to a winning cluster or a Wild Pair Explosion.

Wild Pair Explosion

If there are any electric wild pairs remaining at the end of a round, this triggers the wild pair explosion. If the electric wilds are next to each other, all other symbols on the grid (except wilds) are removed. If the electric wilds are not next to each other, all symbols between them and surrounding symbols are removed. These removed symbols also add charge to the Quantumeter!

RTP of Reactoonz 2

The Return to Player of Reactoonz 2 is 94.2%, placing it on the lower end of the scale in terms of maximum payout over time.

Tricks of Reactoonz 2

With such a slew of effects, it's hard not to trigger something on every hit of that 'spin' button! What you do want to look out for to maximise your win potential is a mixture of cascading wins with the fluctuating symbols and electric wilds, so you can charge both meters at the same time.

Fill them both within one round and you'll get up to 3x electric wilds added followed by the appearance of that massive 3x3 Gargantoon wild, which breaks down to 2x2 wilds then single wilds. That's a lot of win potential right there! Even if you don't manage to fill the Quantumeter all the way up to Level 3 or 4, you'll still get Energoon wilds to help you make additional wins.

Should You Play This Game?

A game like this that's bursting with multiple ways to win gives you many reasons to play, but here are our top five:

  • Comical alien theme: You gotta love those cute one, two and three-eyed aliens as they cascade and pop all over the grid!
  • Awesome sounds: The cosmic sound effects, alien babbling and synthpop music make this an energetic and intense game to play!
